[hive] flutter pub add hive_flutter
The current Dart SDK version is 3.5.0.

Because hive_flutter >=1.0.0-nullsafety.0 <1.0.0 depends on hive ^1.6.0-nullsafety.0 and hive_flutter >=2.0.0-dev depends on hive ^3.0.0-dev, hive_flutter >=1.0.0-nullsafety.0 <1.0.0 or >=2.0.0-dev requires hive ^1.6.0-nullsafety.0 or ^3.0.0-dev.
And because hive_flutter <1.0.0-nullsafety.0 doesn't support null safety, hive_flutter <1.0.0-∞ or >=2.0.0-dev requires hive ^1.6.0-nullsafety.0 or ^3.0.0-dev.
And because hive_flutter >=1.0.0 <1.1.0 depends on hive ^2.0.0 and hive_flutter >=1.1.0 <2.0.0-dev depends on hive ^2.0.4, every version of hive_flutter requires hive ^1.6.0-nullsafety.0 or >=2.0.0 <3.0.0 or ^3.0.0-dev.
So, because hive depends on hive_flutter any and hive is 1.0.0+1, version solving failed.

The lower bound of "sdk: '>=2.2.2 <3.0.0'" must be 2.12.0 or higher to enable null safety.

Reproduce the reported `flutter pub add hive` and `flutter pub add hive_flutter` failures with Dart SDK 3.5.0. Inspect the package SDK and dependency constraints for `hive` and `hive_flutter`; done means dependency resolution succeeds while retaining null-safety support.
